The machine of the present invention is designedand adapted primarily for making buttons from mother-of-pearl, Celluloid, bone, horn,v

composition, and other materials. It is understood, howeven'that the machine may have other uses. In the manufacture of buttons, blanksare first cut from the desired material, the blanks are then faced, and then said blanks have holes drilled therein. The machine with its appurtenances and attachments is capable of carrying out the aforesaid distinct operations and does not require individual machines to accomplish the same as is now the practice.

The machine includes a bed or base II) consisting of longitudinal members II arranged in spaced parallel relation, and cross members i2 disposed, respectively, at the adjacent ends of the members Il and are secured thereto in any suitable manner as by the employment of lstuds y I 3, one of which is indicated in dotted lines in Fig. 8. The cross members I 2 provide feet for the base at the opposite ends thereof. A pedestal I4 having axially alined bearings I5 yand I6, respectively, is secured to the members II by suitable fastening elements I'I at the left-hand end of the base I0. A hollowr spindle I8Y is supported for rotation by the bearings I5 and I6. A duplex pulley IS is mounted on the spindle I8 and is made fast thereon by a set screw 20. The pulley IS is arranged between the bearings I5 and I6 and is of a size to abut against these bearings. It will therefore be understood that the pulley IS as arranged will prevent the axial movement of the spindle I8. The pulley I9 serves for the purpose of rotating the spindle VI8 when driven by a suitable belt. 'I'he inner end o f the spindle I8 has a head 2| having threads 22 and a circular flange 23. A barrel or hollow stock 24 has threads complemental to the threads 22 in order to be detachably connected with the head 2l. The stock 24 carries a chuck 25 consisting of a body 26 having a tapped bore 2'I therein and resilient jaws 28 integral with the body 26. A rod 29 has ahead Si) on one end thereof. A threaded extension SI integral with the head and in axial alinement with the head 29 is adapted to be screwed into the bore 2'I in order to detachably connect the rod 29 with the chuck 25. The rod 29 is of a diameter'to loosely extend through the hollow spindle I8 in order to slide or be axially movable in the spindle I8, while the chuck 25 may have axial movement in opposite directions with respect to the stock 24. The head 30 has a longitudinal groove 32 in the periphery thereof which accommodates the inner end of a key inA the form of ascrew 33 carried by thel stock 24. The key 33 engaged in the groove 32 prevents rotation of the chuck elements 46.

25 while permitting axial movement thereof. Means 34 on the stock 24 coacts with means 35 on the chuck 25 to cause the jaws 28 to ex inwardly to grip a button blank when the chuck 25 moves axially rearward, and said means allows the jaws 28 to swing outwardly to a normal relation in order to release the blank when the chuck moves axially outward. The means 34 is in the form of a corneal wall provided by an opening in the forward end of the stock 24, and the means 35 consists of inclined surfaces, respectively, of the jaws 28. Resilient means in the form of a coil spring 36 serves to move the chuck 25 axially inward to cause the jaws to grip a button blank until released. `'Ihe spring 36 is arranged within the stock 24 surrounding the jaws and body 26, and one end of the spring bears against the stock and its opposite end bears against the head 30. The movement of the rod 29 axially forward causes a similar movement of the chuck 25 in order to release the blank held by the jaws 28.

Means is provided for supporting either a material holder or a tool holder according to the operation to be performed. The said means consists of a pedestal 49 having a bearing 4I which is secured to the members II by fastening elements 42 at the extreme right-hand end of the base I0. Also a pedestal 43 having a bearing 44 is positioned in spaced relation to the right of the pedestal I4 for sliding movement on top of the members II. A slide 45 is secured to the pedestal 43 on the under side thereof by fastening The members II of the base being in spaced parallel relation lprovide a guideway 41 in which the slide 45 moves guided by the I members II. VThe bearings 4I and 44 are in axial alinement with each other and also in axial alinement with the spindle I8.

Motion transmission mechanism operated in response to the rotation of the spindle I8 serves to cause thel axial forward movement of the rod 29 and its chuck 25, and also to reciprocate or cause the sliding movement of the pedestal 43 in opposite directions. The said mechanism includes a small gear 48 fast on the spindle I8 beyond the bearing I5. The gear 48 meshes with a large gear 49 rotatable on an arbor 59 carried by a bracket I on the pedestal I4. vThe gear 49 meshes with a small gear 52 fast on one end of a shaft 53. The shaft 53 is supported by bearings embodied by a casing 54. This casing is securely held in place on a bracket 55 secured to the base I0. The shaft 53 carries a worm 56 which meshes with a worm gear 51 fast on a shaft 58 supported for rotation by a bearing 59 which is a part of the casing 54. The worm 56 and gear 51 are arranged within the casing 54. A gear 60 fast on the outer end of the shaft 58 meshes with a large gear 6| journaled for `rotation on a stub shaft 62 carried by the bracket 55. The gear 6| has formed yintegral therewith and concentric thereto a disk 63. A similar disk 64 is mounted for rotation on a stub shaft 65 carried by a bracket 66 secured to the base I0. The shaft 65 is in axial alinement with the shaft 62. A wrist pin 61 is supported by the disks 63 and 64 between the same since these disks are arranged in spaced relation to each other. These disks, together with the pin 61, constitute a, crank. A pitman 68 has one end thereof connected with the pin 61 and itsv opposite end is pivotally connected, as at 68, with vone end of a slide arranged in the guideway 41. The slide 10 rests on cross pieces 1I and 12 respectively secured to the members II on the under side thereof. The slide 1I) is connected with the slide 45 by a connecting rod 13 whose opposite ends 14 and 15 have right and left threads received in tapped holes 16 and 11, respectively, in the slides 10 and 45. It will now be understood that the pedestal 43 will be moved or slid back toward the pedestal 40 and therefore toward the pedestal I4kin response to the rotation of the spindle I8 and by virtue of the intervention of the gear train, crank, pit- .man and connected slides hereinbefore described.

When it is desired to cut button blanks from a piece of material, such as mother-of-pearl or the other materials mentioned, use is made of a suitable support 83 consisting of a hollow abutment 8| having a stock in the form of a shaft 82, as shown in Fig. '7. This shaft 32 is of a size to loosely fit in the bearings 4| and 44. The support 89 is held against movement by a set screw-83 carried by the bearing 44. Use is made of a tubular cutter 84 which is held by a chuck 85 of conventional type which is adapted for connection with the head 2|. In other words, the chuck 85 is screwed on the head until it abuts the flange 23. The chuck 85 and its cutter 84 rotate with the spindle I8, and appear in Fig. 7. A piece of material from which the button blanks are cut is designated 86. This material is held against the abutment 8| by the operator attending the machine. As the pedestal 43 is slid back and forth, the support 80 will be moved likewise. Consequently, the material 86 will be fed intermittently to the cutter 84 which will cut out a circular button blank. Each time the support 89 is advanced to the cutter 84 the material 86 is shifted by the operator to produce as many button blanks as possible from the material. l

In order to carry out the facing operation on the blanks use is made of a tool holder 9|) including a round stock 9| and a clamp 92 carried by the forward end of the stock 9|. The stock 9| may extend through the bearings 4I and 44 to be supported thereby. The set screw 83 serves to hold the tool holder 9) in fixed position in order that it will reciprocate with the pedestal 43. A suitable facing tool 93 is held in'positon by the clamp 92. The clutch unit 25 is applied to the spindle head 2| by screwing the stock 24 into threading engagement therewith. A set screw 5 carried by the stock 24 and engageable with the head 2| holds the chuck against rotation with respect to the spindle I8 but causes the chuck to rotate with it. The tool holder- 90 and the chuck unit 25 appear in Figs. 1 and 2 of the drawings in use.

In order to cause the chuck 25 to move outwardly to release a button blank and to subsequently receive a new blank after the previous blank has been faced, there is provided a lever 94 which is fulcrumed as at 95 on the pedestal I4 and casing 54. The end 96 of the lever carries an adjusting screw 91, and the other end 98 of the lever has a roller 99. A cam |80 is detachably secured to the crank disc 64 by fastening elements IOI. This cam is a doubleacting cam having two cam portions or high points |92 and |63, respectively, and an intervening notch |04. The cam |00 cooperates with the lever 94 in the rotation of the crank disk 64. The cam is arranged in advance of the pin 61. When the cam portion |02 acts on the roller 99, the lever 94 will be moved causing the screw 91 on the end 96 to bear on the rod, causing the clutch 25 to move forwardly and release a button blank which has been previously faced by the facing tool 93. The spring 36 causes retraction of the chuck 25 together with the rod 29 due to the fact that the roller 99 drops into the notch |94. This is immediately followed by the cam portion |92 imparting movement to the lever 94 which, in turn, operates the rod 29, causing the chuck 25 to again move forwardly, whereupon the jaws 28 will spring outwardly to enable an operator to insert a new button blank into the chuck as it is being retracted by the spring 36 when the roller 99 drops behind the cam portion |03. While the button blank is being inserted in the chuck 25, the tool holder 9D is in its fully retracted position to enable the insertion of the button blank without injury to the operator. The tool holder 90 moves forwardly to engage the facing tool 93 with the new button blank, which removes material of the blank to form the usual annular rim or bead, as shown in Fig. 6. The button blank is designated |D5 and the rim formed by the tool 93 is designated |06. As the disk 64 continues to rotate the operation hereinbefore described is repeated. As the blanks are released from the chuck 25 they drop in a tray |01 carried by the pedestal 43. It is to be understood that when cutting out blanks by the use of the attachments 30 and 85, the cam |06 will be detached from the disk 64 and the lever 94 will also be detached since these parts are not required.

In order to carry out the hole drilling operation, use is made of the clutch unit 25 whose spindle is extended through the bearings 4| and 44, the set screw 83 serving to hold the unit in place so as to reciprocate with the pedestal 43, as shown in Fig. 8. A bracket |08 is secured to the right-hand end of the base I9. An adjusting screw |09 is carried by the bracket |98 and is disposed in axial alinement with the rod 29, in order to actuate the rod 29 each time the pedestal 43 is moved to the limit of its rearward travel. This causes the clutch 25 to release the drilled button. As the pedestal 43 moves forwardly a new blank may be inserted in the clutch for the drilling operation.

A drill unit |49, shown most clearly in Fig. 9, is used for drilling holes in the blanks and in the present instance this unit drills four holes, although a lesser number may be drilled in the blanks. The drill unit consists of a stock H providing a threaded socket which may be screwed on to the head 2|, and an extension ||2 integral with the socket and disposed centrally thereof, which is provided with a pinion |3. The set screw securely holds or locks the stock H0 on the head 2| so as to rotate with the spindle I8. A barrel I4, equal in diameter to the socket has a roller bearing |42 in one end, said bearing being held in place by a set screw |43. Drills |44 are supported by bearings |45, |46 and |41, respectively. These bearings |45, |46 and |41 are held in place within the barrel |4| transversely thereof by set screws |48, |49 and |50, respectively, carried by the barrel. The drills |44 are arranged in a forwardly converging relationship. Each drill shaft has fast thereon a pinion |5| which meshes with the pinion ||3. The barrel |4| is held in fixed position by means of set screws |52 carried by a bracket |53 secured to the base members by fastening elements |54. This bracket |53 also carries a bearing |55 which steadies the bits |56 of the drills |44. The bits |56 project slightly beyond the bearing |55. Inasmuch as the barrel |4| is held stationary the drills |44 will not be permitted to planetate about the axis of the spindle i8, but will be permitted to rotate on their own axes. This is caused by the rotation of the spindle |8, which causes the pinion H3, through the intervention of the stock H9, to rotate the pinions |5|, causing the rotation of the drills and their bits. As each faced button blank is presented by the clutch unit 25 in the forward travel of the pedestal 43 by the action of the crank, four holes will be drilled in the blank, after which the latter is dropped into a tray |51 placed on the pedestal 43. It is understood that the tray |51 is substituted for the tray |01.

From the foregoing it will be understood that the machine is readily convertible for carrying out button blank cutting operations, facing operations, and drilling operations by reason of the interchangeable use of the chuck unit 25, the Work or material support 85, the tool holder 90, and the drill unit |49.

It will also be apparent that the machine automatically provides for uniform thickness of the buttons; and that adjustments may be readily made which enable the blank cutting, facing and drilling operations to be carried out on materials of different thicknesses.

I claim:

1. In a button making machine, a reciprocatory tool holder, a hollow chuck spindle, a chuck operating rod extending through said spindle having axial movement as well as rotary movement, and mechanism operated by said spindle upon the rotation of the latter to reciprocate the tool holder and to cause the axial movement of said rod, said mechanism comprising a crank, gearing operated by the spindle, said crank being connected with and operated by said gearing, a
